Chapter 10
Put in the voltage supply from the power pack into the power supply from the system on the
connection panel.
NOTE!
After connecting the power supply into the system, a brief self test is starting for approx 5
minutes. After the brief self test the system begins to produce pure and ultrapure water.
If the tank content of the Puranity TU 3+/6+ system is empty it is possible that air is
coming from the tank into the ultrafilter (only systems with ultrafilter). Thereby you can
not dispense water from the sampling tap on the system. Proceed as follows in such a
case:
unplug the main plug and wait 5 seconds before you put the main plug back.
Wait approx 10-15 minutes before you start with dispensing water from the sampling
tap.
Wait until the tank filling has been completed. This could take approx. 1.5 to 3 hours with a
Puranity TU 3+/6+ system. With a Puranity TU 12+ system this could take up to 2.5 hours to
fill a 30L tank and about 5 hours to fill a 60L tank. Discard the content of first tank filling.
Before screw in the sterile filter onto the dispensing valve outlet, wait until the tank have the
maximum capacity and leave approx 2-run 3 liters pure water from the dispensing valve.
Screw in the sterile filter.
